The foot-actuated of the hand-lever 14, which is extended withraising and lowering devices herein shown comprise the raising-lever 27 and the lowering-lever 28, journaled or mounted on a common axis on the side bar 2 of the machineframe.

Referring to Fig. 6, the lowering-lever is secured to a hub 29 by a bolt 30, which hub is journaled in the bearing-bracket 31, secured to the bar 2. The lowering-lever is forked, one of the forks having a footpiece, preferablya pivoted stirrup 32, the other fork being connected by a link 33 to a bracket 34, fastened to the plow-beam, Figs. 1 and 6. The raising-lever 27, which also preferably has a pivoted stirrup 35, is pivoted intermediate of its length on the hub 29 and is also connected to the plow-beam by means of a link 36, which is pivoted atits lower end to the bracket and intermediate of its length to the raising-lever. Inasmuch as the general operation of these levers is the same as that of the similar levers shown in our prior patent,

No. 704,274, dated July 8, 1902, further explanation and description is rendered unnecessary.-

The relative position of the various movable parts when the hand and foot levers are working conjointly is illustrated in Figs. 2 and 3, the former figure showing the lowered position of the plow and the latter figure the raised position thereof. Starting with the parts as shown in Fig. 2 and assuming that the plow is to be raised and that the handlever is already in engagement with the notched link, the raising-lever 27 is forced forward by the riders foot and simultaneously the hand-lever is drawn backward, the plow being maintained in raised position by the locking effect of the foot-levers. The hand-lever may now, if desired, be released as to its latch from engagement with the notched link, and if so released it may be brought to rest, pointing forwardly or rearwardly, with its stop 26 contacting the top edge of the side bar 1.

When it is desired to lower the plow with the conjoint action of the hand and foot devices, the hand-lever is caused to engage the notched link and the lowering-lever is forced forwardly by the foot and the hand-lever likewise moved forwardly with pressure of the hand, or such hand-lever may be used to prevent too-rapid movement of the plow. Of course it will be understood that the raising and lowering of the plow may be accomplished by the separate or the conjoint action of the hand and foot devices. In the normal condition of the parts the hand-lever is unconnected with the curved link, and therefore also unconnected with the plow, for such hand-lever obtains connection with the plow only through the medium of this curved link. The latch 20 is, as hereinbefore stated, of such character as to be normally held out of engagement with the curved link, and consequently during such normal position or condition of the hand-lever and whenever thefoot-leversare operated for the purpose of raising or lowering the plow without the aid of the hand-lever the curved link will float with respect to the lever.

We claim- 1. In a plow, the combination of a frame, a plow supported therein, a link pivoted to the plow and a hand-lever having a movement independent of the plow but arranged to be connected to or disengaged from the link; substantially as described.
